BANDAGE-ROLLING MACHINE.

Specification of Letters Patent.

Patented Nov. 16, 1920.

Application filed March 27, 1918. Serial No. 225,053.

(:71 whom it may concern:

Be it known that I, Tnnnssn A. BLAIR, a citizen of the United States, residing at Marquam, in the county of Clackamas and State of Oregon, have invented certain new and useful Improvements in Bandage-Rolling Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in bandage rolling machines and has for one of its objects the provision of a device of this character whereby a strip of bandage may be readily and conveniently wound into a roll, so that the same can be conveniently applied to wounds.

Another object of this invention is the provision of a spindle having means connected thereto for supporting and rotating the same so that a strip of bandage mate rial may be readily wound thereon and which can be disconnected from said means after the bandage has been rolled, so that the roll can be removed from said spindle.

A further object of this invention is the provision of a bandage rolling machine of the above stated character, which shall be simple, durable and eflicient, and which may be manufactured and sold at a comparatively low cost.

With these and other objects in view as will become more apparent as the description proceeds, the invention consists in certain novel features of construction, combination, and arrangement of parts as will be hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had to the following description and accompanying drawing, in which Figure 1 is a side elevation of a bandage rolling machine constructed in accordance with my invention,

Fig. 2 is a vertical sectional view of the same,

Fig. 3 is a transverse sectional view illustrating an internal gear meshing with a pinion carried by a drive shaft,

Fig. 4 is a fragmentary vertical sectional view of the means for connecting the spindle to the driving shaft, and

Fig. 5 is a plan view of a disk.

Referring in detail to the drawing, the numeral 1 indicates a vertical upright havmg formed upon its lower end a pair of relatively spaced lugs 2 which are adapted to engage the upper and lower faces of a table or l1ke support 3. The lower lug is provided with a screw threaded opening to receive a set bolt 4 provided with a head 5 and a handle 6, which head is adapted to be turned into engagement with the table or support 3 by turning the set bolt 4 by the handle 6 to tightly clamp the the upper lug 2. The horizontally disposed bearing is formed upon the upper end of the vertical upright 1 and has journaled therein a shaft 8 carrying at one end a pinion 9. The pinion 9 is in mesh with an internal gear 10 journaled to a stub shaft 11 secured to the vertical upright 1. The internal gear 10 has secured thereto a handle 12 for the purpose of rotating the same so that the shaft 8 may be rotated.

The other end of the shaft 8 has formed thereon an enlarged'head 18 provided with a hexagonal opening or socket adapted to removably receive a hexagonal shaped spindie 14 and which is detachably secured within the socket by means of a set screw 15, carried by the head 13. A circular disk 16 is provided with a hexagonal opening 17 to receive the spindle 14 and is moved in engagement with the head 13 so that bandages when wound upon the spindle will not come in contact with the head 13 and thereby be prevented from becoming mutilated or the edges of the material crimped.

In operation, the device is secured to a support or table top and a strip of bandage material is then wound about the spindle 14 once or twice and the operator then holds the material in one hand permitting it to move freely through the fingers and rotate the internal gear 10 by the handle 12 which drives the spindle l4 winding the material thereon.

The spindle 14 being of hexagonal shape causes the strip of material to readily wind thereon without slipping. By holding the strip of bandage material in one hand and permitting the same to move or slide freely through the fingers, the same can be readily fed on to the spindle 14 by rotating the gear 10 by the handle 12. The bandage material is first turned manually several times about the spindle before the regular operation of support to l the machine is started. After the entire strip of bandage material has been wound upon the spindle 14:, in roll form, the roll is gripped by the fingers of the operator and the spindle 14 is turned slightly in a reverse direction by turning the handle 12 in a reverse direction thereby loosening the roll of bandage material upon the spindle. The operator then places the fingers of one hand against the disk 16 and pulls the disk oif of the spindle 1 carrying with the same a roll of bandage material. By removing the roll of bandage material from the spindle in the above manner prevents the edges of the material from being crimped or mutiliated. After the roll of bandage material has been removed by sliding the disk 16 cit of the spindle 14:, the disk is again placed on the spindle 14 as illustrated in Fig. 2 placing the device ready for the next operation of the machine. The disk 16 is so mounted upon the spindle 14 that the same can be readily removed and replaced upon the spindle when desired.

\Vhile l have shown and described the preferred embodiment of my invention, it will be understood that minor changes in corn struction, combination, and arrangement of parts, may be made without departing from the spirit and scope of the invention as claimed.

Having thus described my invention, what I claim as new is A bandage rolling machine comprising a vertical support, a horizontal bearing formed on the upper end of said support, a shaft on said spindle and adapted to be manually slid on said spindle in the direction of its free end to remove a roll of bandage there from without crimping the edges of said bandage, a. gear secured tothe other end of the shaft, aninternal gear journaled to the support below the bearing-and in mesh with said gear, and a handle secured to said internal gear.

In testimony whereof I afiix my signature in presence of two witnesses.
